In many industries, the occurrence of short period power drops and fluctuations lead to many problems such as machine stoppage which increases amount of waste generation, product defects and reduction of productivity. This paper focuses on a research carried out to design and implement an Intelligent Automatic Switching Device for machinery in the event of power fluctuations. In the case of short term power dips or cuts the device reactivates the machinery automatically. The paper highlights the three main advantages of this automation, namely, minimizing waste generation, increasing productive time and minimizing defects. The concept developed through the research was applied to automate Weaving looms. The paper also looks at how this concept can be applied to suit any industry.

Maximization of power, which depends on solar irradiation and temperature conditions, from a photo voltaic (PV) generator is of special interest as the efficiency of the PV module is very low. A maximum power tracker is used for extracting the maximum power from the generator. To be effective with cellular converter architecture, however, a scheme must be able to accommodate a varying number of cells and maintain operation under any climate conditions. Three types of PWM pulses (synchronized pulses, independent pulses, and interleaved pulses), applied to switches, to extract maximum power from PV generator are employed. Quantitative performance comparisons are being presented among synchronized pulses, independent pulses, and interleaved pulses of the converter cells. Simulation is done in MATLAB simulink environment.

The increased use of high frequency electronic equipment in modern day technologies causes electromagnetic interference with each other. To avoid this, the detection of unwanted electromagnetic radiations is required in industry where electromagnetic interference and compatibility (EMI/EMC) problems are quite an important issue. For EMI measurement, it is required to place a sensor to receive the radiation from the equipment. In this paper, a dielectric loaded T-shaped ultra wideband monopole antenna is designed and used as sensors for measuring electromagnetic interference. The performance of a sensor depends on its antenna factor, which is the ratio of the incident electric field on the antenna surface to the received voltage at the load end. Here the antenna factor of the same antenna is presented for the desired and cross polarization of the incident field. The results for antenna factor show an ultra wide bandwidth with the cross polarization isolation better than 86 dB / m for the T-monopole / DRA as EMI sensor. The simulated return loss characteristics show well agreement with the measured data of a prototype antenna.
在现代技术中，高频电子设备的使用越来越多，导致彼此之间产生电磁干扰。为了避免这种情况，在工业中需要检测有害的电磁辐射，其中电磁干扰和兼容性(EMI/EMC)问题是相当重要的问题。对于电磁干扰测量，需要放置一个传感器来接收来自设备的辐射。本文设计了一种载介质的t型超宽带单极天线，并将其作为电磁干扰传感器。传感器的性能取决于其天线因子，即天线表面的入射电场与负载端接收电压的比值。本文给出了同一天线在入射场的期望极化和交叉极化情况下的天线因子。天线因子分析结果表明，t单极子/ DRA作为电磁干扰传感器具有超宽的带宽，交叉极化隔离优于86 dB / m。模拟的回波损耗特性与原型天线的实测数据吻合良好。

This paper compares the methods that have been used to control frequency in the recently deregulated power system in Sri Lanka with the highly deregulated power system in Great Britain. Also it presents the proposed methods found from a literature survey that use demand side support for frequency control. It also emphasises the need of commercial and demand side arrangements in frequency control in order to safe guard the assets of a public utility and also to ensure cost effective operation of future Sri Lankan power system.

This paper focuses on numerical simulations of positive dc corona in air in coaxial cylindrical electrode arrangement. The study aimed at developing a computer model accounting for background physical processes in corona discharge and its verification by means of comparison of calculated corona characteristics with experimental data. Several parameters of corona, namely, inception voltages, voltage current characteristics and onset field strength values were used for evaluations of the model performance. The validated model was further utilized to investigate the effects of ion mobilities on corona current and variations of the ionization intensity on corona inception voltages.
